DFT study on second-order nonlinear optical properties of a series of mono Schiff-base M(II) (MÂ =Â Ni, Pd, Pt) complexes

Density Functional Theory (DFT) was employed to investigate the second-order nonlinear optical (NLO) properties of mono Schiff-base M(II) (M = Ni, Pd, Pt) complexes. It is found that the second-order NLO properties of the metal complexes are intensively sensitive to the exchange of donor/acceptor.
